Description

Technical Field

[0001] This utility model relates to the field of sealing foam tape processing technology, specifically a sealing foam tape processing and bonding device. Background Technology

[0002] Foam tape is made by coating one or both sides of EVA or PE foam with solvent-based (or hot-melt) pressure-sensitive adhesive and then covering it with release paper. To improve the production efficiency of the tape, a bonding device is usually used to bond the materials together.

[0003] According to publication number CN219585486U, a foam and adhesive tape bonding device includes a support mechanism, a foam roller mechanism, an adhesive tape roller mechanism, and a pressing mechanism. The foam roller mechanism, adhesive tape roller mechanism, and pressing mechanism are all fixedly connected to the support mechanism. The bonding device also includes a leveling mechanism, which is fixedly connected to the support mechanism and maintains tension on the foam and adhesive tape during transport. In this invention, the foam roller mechanism, adhesive tape roller mechanism, pressing mechanism, and leveling mechanism are all mounted on the support mechanism. The leveling mechanism maintains tension on the foam and adhesive tape during transport, ensuring proper bonding of the foam and adhesive tape on the pressing mechanism, guaranteeing bonding stability and accuracy, reducing errors, and thus improving bonding efficiency.

[0004] The flat structure described above can ensure the tension of the foam and tape during conveying. However, during the conveying process, external factors such as airflow can easily cause the tape to become loose or wrinkled, thus affecting the bonding accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a sealing foam tape processing and bonding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing foam tape processing and bonding device, comprising a support platform, a connecting frame fixedly connected to the top of the support platform, a connecting plate fixedly connected to the side of the support platform away from the connecting frame, guide grooves being provided in the middle of both the connecting plate and the connecting frame, a first motor fixedly connected to the side of the connecting plate away from the connecting frame, a bidirectional lead screw fixedly connected to the output end of the first motor, a threaded sleeve threadedly connected to the surface of the bidirectional lead screw, a rotating plate rotatably connected to the left side of the threaded sleeve, a connecting block rotatably connected to the bottom of the rotating plate, a lifting plate fixedly connected to the side of the connecting block away from the rotating plate, a first spring fixedly connected to the top of the lifting plate, an upper guide roller fixedly connected to the top of the first spring, a second spring fixedly connected to the bottom of the lifting plate, and a lower guide roller fixedly connected to the bottom of the second spring.

[0007] As a further preferred embodiment of this technical solution, the bidirectional lead screw passes through the connecting plate and is rotatably connected to the connecting frame. There are two threaded sleeves, and the number of the rotating plate and the number of threaded sleeves correspond to each other. The lifting plate is located inside the guide groove, and there are moving blocks on both sides of the upper guide roller and the lower guide roller. The moving blocks are adapted to the guide groove.

[0008] As a further preferred embodiment of this technical solution, a connecting housing is fixedly connected to the side of the connecting frame away from the connecting plate, and a second motor is fixedly connected to the side of the connecting housing away from the connecting frame. A drive wheel is fixedly sleeved on the output shaft of the second motor, and a toothed belt is engaged on the surface of the drive wheel. A transmission wheel is engaged on the inner wall of the toothed belt.

[0009] As a further preferred embodiment of this technical solution, both the transmission wheel and the drive wheel are fixedly connected to an installation roller, and a connecting screw is fixedly connected to the side of the installation roller away from the connecting frame. A limit plate is provided on the surface of the connecting screw, and a threaded hole is opened inside the limit plate.

[0010] As a further preferred embodiment of this technical solution, an adjusting roller is rotatably connected to the side of the connecting frame near the mounting roller, a first bracket is fixedly connected to the top of the support platform, a cylinder is fixedly connected to the top of the first bracket, a mounting frame is fixedly connected to the bottom of the cylinder, a guide rod is fixedly connected to the top of the mounting frame, and a pressure roller is rotatably connected inside the mounting frame.

[0011] As a further preferred embodiment of this technical solution, the adjusting roller is located on the side of the lifting plate away from the mounting roller, the first bracket and the connecting frame are fixedly connected, and the top of the first bracket is provided with a through hole, which is adapted to the guide rod.

[0013] This utility model provides a sealing foam tape processing and bonding device, which has the following beneficial effects:

[0014] (1) By starting the first motor, the output shaft of the motor drives the bidirectional lead screw to rotate, the threaded sleeve slides, the rotating plate rotates between the threaded sleeve and the connecting block, and pushes the lifting plate to slide inside the guide groove, thereby adjusting the position of the upper guide roller and the lower guide roller. After the foam and tape are installed, the upper guide roller and the lower guide roller are squeezed to one side of the lifting plate respectively. The first spring and the second spring are squeezed and contracted. When the foam and tape become loose or wrinkled due to external factors, the upper guide roller and the lower guide roller are moved back under the elastic force of the first spring and the second spring, so that the material tape is taut again to ensure the accuracy of the bonding.

[0015] (2) By setting a connecting screw on one side of the installation roller, when it is necessary to install the tape and foam tube, the limit plate is rotated by the handle. After rotating a certain number of times, the limit plate is disengaged from the connecting screw, and the tape and foam tube are installed on the installation roller. The limit plate is then installed on the connecting screw again, which fixes the position of the tube. By controlling the position of the limit plate, tubes of different sizes can be limited to avoid the tape from shifting during the bonding process. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1 to 5 As shown, in this embodiment, a sealing foam tape processing and bonding device includes a support platform 1. A connecting frame 2 is fixedly connected to the top of the support platform 1. A connecting plate 3 is fixedly connected to the side of the support platform 1 away from the connecting frame 2. Guide grooves 4 are provided in the middle of both the connecting plate 3 and the connecting frame 2. A first motor 5 is fixedly connected to the side of the connecting plate 3 away from the connecting frame 2. A bidirectional lead screw 6 is fixedly connected to the output end of the first motor 5. A threaded sleeve 7 is threadedly connected to the surface of the bidirectional lead screw 6. A rotating plate 8 is rotatably connected to the left side of the threaded sleeve 7. A connecting block 9 is rotatably connected to the bottom of the rotating plate 8. A lifting plate 10 is fixedly connected to the side of the connecting block 9 away from the rotating plate 8. A first spring 11 is fixedly connected to the top of the lifting plate 10. An upper guide roller 12 is fixedly connected to the top of the first spring 11. A second spring 13 is fixedly connected to the bottom of the lifting plate 10. A lower guide roller 14 is fixedly connected to the bottom of the second spring 13.

[0024] The first motor 5 is started, and its output shaft drives the bidirectional lead screw 6 to rotate. The threaded sleeve 7 slides, and the rotating plate 8 rotates between the threaded sleeve 7 and the connecting block 9, pushing the lifting plate 10 to slide inside the guide groove 4, thereby adjusting the position of the upper guide roller 12 and the lower guide roller 14. After the foam and tape are installed, the upper guide roller 12 and the lower guide roller 14 are squeezed towards one side of the lifting plate 10, and the first spring 11 and the second spring 13 are squeezed and contracted. This application employs a "tension adjustment mechanism" consisting of a first motor 5, a bidirectional lead screw 6, a first spring 11, an upper guide roller 12, a second spring 13, and a lower guide roller 14 to achieve two adjustment mechanisms. One is a linkage adjustment mechanism between the upper guide roller 12 and the lower guide roller 14 when the motor is working, which achieves initial tensioning of the material strip on the two mounting rollers 20 at the adjustment roller 24. The other is an automatic tension compensation mechanism that achieves independent adjustment of the cooperation between the spring 11 and the upper guide roller 12 or the cooperation between the second spring 13 and the lower guide roller 14, either simultaneously or at different times. That is, the upper guide roller 12 and its cooperating first spring 11 constitute the first independent tensioning assembly, and the lower guide roller 14 and its cooperating second spring 13 constitute the second independent tensioning assembly. When the upper foam strip becomes slack for any reason, the first spring 11 will push the upper guide roller 12 to move independently to tighten the strip. This process does not affect the tension of the lower adhesive tape. Similarly, when the lower adhesive tape becomes slack, the second spring 13 will push the lower guide roller 14 to move independently to restore its tension, which also does not affect the upper foam strip. This combination of "overall coarse adjustment" and "independent fine adjustment" ensures that the two strips maintain a proper and independent tension during the conveying process, thereby effectively guaranteeing the accuracy of the bonding.

[0025] The bidirectional lead screw 6 passes through the connecting plate 3 and is rotatably connected to the connecting frame 2. There are two threaded sleeves 7. The number of rotating plates 8 and threaded sleeves 7 are corresponding. The lifting plate 10 is located inside the guide groove 4. Moving blocks are provided on both sides of the upper guide roller 12 and the lower guide roller 14. The moving blocks are adapted to the guide groove 4.

[0026] A connecting housing 15 is fixedly connected to the side of the connecting frame 2 away from the connecting plate 3. A second motor 16 is fixedly connected to the side of the connecting housing 15 away from the connecting frame 2. A drive wheel 17 is fixedly sleeved on the output shaft of the second motor 16. A toothed belt 18 is engaged on the surface of the drive wheel 17. A transmission wheel 19 is engaged on the inner wall of the toothed belt 18.

[0027] The second motor 16 is started, and its output shaft drives the drive wheel 17 to rotate. The toothed belt 18 rotates accordingly and transmits power to the transmission wheel 19, thereby driving the two mounting rollers 20 to rotate, so as to realize the simultaneous feeding of the two material belts and avoid the error of feeding speed caused by different rotation speeds.

[0028] Both the transmission wheel 19 and the drive wheel 17 are fixedly connected to the interior of the mounting roller 20. The mounting roller 20 is fixedly connected to the side away from the connecting frame 2 with the connecting screw 21. The surface of the connecting screw 21 is provided with a limit plate 22, and the interior of the limit plate 22 is provided with a threaded hole 23.

[0029] Install the tape and foam tube on the mounting roller 20, rotate the handle to install the limiting plate 22 on the connecting screw 21 and abut against one side of the tube, thus fixing the position of the tube. By controlling the position of the limiting plate 22, tubes of different sizes can be limited to avoid the tape from shifting during the bonding process.

[0030] An adjusting roller 24 is rotatably connected to the side of the connecting frame 2 near the mounting roller 20. A first bracket 25 is fixedly connected to the top of the support platform 1. A cylinder 26 is fixedly connected to the top of the first bracket 25. A mounting frame 27 is fixedly connected to the bottom of the cylinder 26. A guide rod 28 is fixedly connected to the top of the mounting frame 27. A pressure roller 29 is rotatably connected inside the mounting frame 27.

[0031] The cylinder 26 is activated, and its output rod drives the mounting frame 27 and the pressure roller 29 to move downward, thereby adjusting the height of the pressure roller 29 to facilitate the installation of the material strip and to achieve the pressing of sealing foam tapes of different thicknesses. At the same time, the guide rod 28 slides inside the through hole of the first bracket 25 to ensure stability during the height adjustment process.

[0032] The adjusting roller 24 is located on the side of the lifting plate 10 away from the mounting roller 20. The first bracket 25 and the connecting frame 2 are fixedly connected. The top of the first bracket 25 is provided with a through hole, which is compatible with the guide rod 28.

[0033] A second bracket 30 is fixedly connected to the top of the support platform 1. A third motor 31 is fixedly connected to the front of the second bracket 30. A take-up roller 32 is fixedly connected to the output end of the third motor 31. The take-up roller 32 is rotatably connected to the second bracket 30.

[0034] By starting the third motor 31, the take-up roller 32 is rotated and the pressed material strip is wound up to facilitate the collection of foam tape. In actual use, the second bracket 30 can adopt a split structure to facilitate the removal of the wound foam tape.

[0035] This utility model provides a sealing foam tape processing and bonding device, the specific working principle of which is as follows:

[0036] In use, the foam and tape cylinders are respectively mounted on the two mounting rollers 20. The tape on the upper mounting roller 20 is wound clockwise around the top of the upper guide roller 12 and the adjusting roller 24, and the tape on the lower mounting roller 20 is wound clockwise around the bottom of the lower guide roller 14 and the top of the adjusting roller 24, and around the bottom of the pressure roller 29. One end of the two tapes is fixed on the take-up roller 32. The handle is rotated so that the limiting plate 22 rotates on the surface of the connecting screw 21 and contacts the tape cylinder to limit it on one side. When bonding, the second motor 16 is started, and its output shaft drives the drive wheel 17 to rotate. The toothed belt 18 rotates accordingly and transmits power to the transmission wheel 19, thereby driving the two mounting rollers 20 to release the material. The cylinder 26 works, and the pressure roller 29 moves down to press the two tapes together. At the same time, the third motor 31 is started so that the take-up roller 32 rotates and winds up the pressed tape to collect the foam tape.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
